BACKGROUND OF THE INVENTION

1. Technical Field of the Invention

This invention relates generally to wireless communication systems and more particularly to integrated circuits of transceivers operating within such systems.

2. Description of Related Art

Communication systems are known to support wireless and wire lined communications between wireless and/or wire lined communication devices. Such communication systems range from national and/or international cellular telephone systems to the Internet to point-to-point in-home wireless networks. Each type of communication system is constructed, and hence operates, in accordance with one or more communication standards. For instance, wireless communication systems may operate in accordance with one or more standards including, but not limited to, IEEE 802.11, Bluetooth, advanced mobile phone services (AMPS), digital AMPS, global system for mobile communications (GSM), code division multiple access (CDMA), local multi-point distribution systems (LMDS), multi-channel-multi-point distribution systems (MMDS), radio frequency identification (RFID), Enhanced Data rates for GSM Evolution (EDGE), General Packet Radio Service (GPRS), and/or variations thereof.

Depending on the type of wireless communication system, a wireless communication device, such as a cellular telephone, two-way radio, personal digital assistant (PDA), personal computer (PC), laptop computer, home entertainment equipment, RFID reader, RFID tag, et cetera communicates directly or indirectly with other wireless communication devices. For direct communications (also known as point-to-point communications), the participating wireless communication devices tune their receivers and transmitters to the same channel or channels (e.g., one of the plurality of radio frequency (RF) carriers of the wireless communication system or a particular RF frequency for some systems) and communicate over that channel(s). For indirect wireless communications, each wireless communication device communicates directly with an associated base station (e.g., for cellular services) and/or an associated access point (e.g., for an in-home or in-building wireless network) via an assigned channel. To complete a communication connection between the wireless communication devices, the associated base stations and/or associated access points communicate with each other directly, via a system controller, via the public switch telephone network, via the Internet, and/or via some other wide area network.

For each wireless communication device to participate in wireless communications, it includes a built-in radio transceiver (i.e., receiver and transmitter) or is coupled to an associated radio transceiver (e.g., a station for in-home and/or in-building wireless communication networks, RF modem, etc.). As is known, the receiver is coupled to an antenna and includes a low noise amplifier, one or more intermediate frequency stages, a filtering stage, and a data recovery stage. The low noise amplifier receives inbound RF signals via the antenna and amplifies then. The one or more intermediate frequency stages mix the amplified RF signals with one or more local oscillations to convert the amplified RF signal into baseband signals or intermediate frequency (IF) signals. The filtering stage filters the baseband signals or the IF signals to attenuate unwanted out of band signals to produce filtered signals. The data recovery stage recovers raw data from the filtered signals in accordance with the particular wireless communication standard.

As is also known, the transmitter includes a data modulation stage, one or more intermediate frequency stages, and a power amplifier. The data modulation stage converts raw data into baseband signals in accordance with a particular wireless communication standard. The one or more intermediate frequency stages mix the baseband signals with one or more local oscillations to produce RF signals. The power amplifier amplifies the RF signals prior to transmission via an antenna.

While transmitters generally include a data modulation stage, one or more IF stages, and a power amplifier, the particular implementation of these elements is dependent upon the data modulation scheme of the standard being supported by the transceiver. For example, if the baseband modulation scheme is Gaussian Minimum Shift Keying (GMSK), the data modulation stage functions to convert digital words into quadrature modulation symbols, which have a constant amplitude and varying phases. The IF stage includes a phase locked loop (PLL) that generates an oscillation at a desired RF frequency, which is modulated based on the varying phases produced by the data modulation stage. The phase modulated RF signal is then amplified by the power amplifier in accordance with a transmit power level setting to produce a phase modulated RF signal.

As another example, if the data modulation scheme is 8-PSK (phase shift keying), the data modulation stage functions to convert digital words into symbols having varying amplitudes and varying phases. The IF stage includes a phase locked loop (PLL) that generates an oscillation at a desired RF frequency, which is modulated based on the varying phases produced by the data modulation stage. The phase modulated RF signal is then amplified by the power amplifier in accordance with the varying amplitudes to produce a phase and amplitude modulated RF signal.

As yet another example, if the data modulation scheme is x-QAM (16, 64, 128, 256 quadrature amplitude modulation), the data modulation stage functions to convert digital words into Cartesian coordinate symbols (e.g., having an in-phase signal component and a quadrature signal component). The IF stage includes mixers that mix the in-phase signal component with an in-phase local oscillation and mix the quadrature signal component with a quadrature local oscillation to produce two mixed signals. The mixed signals are summed together and filtered to produce an RF signal that is subsequently amplified by a power amplifier.

As the desire for wireless communication devices to support multiple standards continues, recent trends include the desire to integrate more functions on to a single chip. However, such desires have gone unrealized when it comes to implementing baseband and RF on the same chip for multiple wireless communication standards. In addition, there is a desire to reduce the number of external components required to implement a wireless communication device.

Therefore, a need exists for an integrated circuit (IC) that implements baseband and RF of multiple wireless communication standards on the same IC die with a reduction in the number of external components needed to implement a wireless communication device.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is a schematic block diagram illustrating a communication system 10 that includes a plurality of base stations and/or access points 12, 16, a plurality of wireless communication devices 18-32 and a network hardware component 34. Note that the network hardware 34, which may be a router, switch, bridge, modem, system controller, et cetera provides a wide area network connection 42 for the communication system 10. Further note that the wireless communication devices 18-32 may be laptop host computers 18 and 26, personal digital assistant hosts 20 and 30, personal computer hosts 24 and 32 and/or cellular telephone hosts 22 and 28. The details of the wireless communication devices will be described in greater detail with reference to one or more of FIGS. 2-23.

Wireless communication devices 22, 23, and 24 are located within an independent basic service set (IBSS) area and communicate directly (i.e., point to point). In this configuration, these devices 22, 23, and 24 may only communicate with each other. To communicate with other wireless communication devices within the system 10 or to communicate outside of the system 10, the devices 22, 23, and/or 24 need to affiliate with one of the base stations or access points 12 or 16.

The base stations or access points 12, 16 are located within basic service set (BSS) areas 11 and 13, respectively, and are operably coupled to the network hardware 34 via local area network connections 36, 38. Such a connection provides the base station or access point 12-16 with connectivity to other devices within the system 10 and provides connectivity to other networks via the WAN connection 42. To communicate with the wireless communication devices within its BSS 11 or 13, each of the base stations or access points 12-16 has an associated antenna or antenna array. For instance, base station or access point 12 wirelessly communicates with wireless communication devices 18 and 20 while base station or access point 16 wirelessly communicates with wireless communication devices 26-32. Typically, the wireless communication devices register with a particular base station or access point 12, 16 to receive services from the communication system 10.

Typically, base stations are used for cellular telephone systems (e.g., advanced mobile phone services (AMPS), digital AMPS, global system for mobile communications (GSM), code division multiple access (CDMA), local multi-point distribution systems (LMDS), multi-channel-multi-point distribution systems (MMDS), Enhanced Data rates for GSM Evolution (EDGE), General Packet Radio Service (GPRS), high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSUPA and/or variations thereof) and like-type systems, while access points are used for in-home or in-building wireless networks (e.g., IEEE 802.11, Bluetooth, ZigBee, any other type of radio frequency based network protocol and/or variations thereof). Regardless of the particular type of communication system, each wireless communication device includes a built-in radio and/or is coupled to a radio.

FIG. 2 is a schematic block diagram of another embodiment of a wireless communication system that includes a communication device 50 associated with a cellular network, a wireless local area network (WLAN) and/or a wireless personal area network (WPAN) 58. The WLAN network is shown to include an access point 54, a local area network (LAN) bus 62, a modem 70, a video source 72, an audio source 74, a printer 68, a personal computer (PC) 76, a facsimile machine (fax) 64, and a server 66, but may include more or less components than shown. The cellular network is shown to include a base station 56, which may support voice communications and/or data communications. Note that the cellular network may include more components than the base station 56. The WPAN 58 includes at least one WPAN device 60 that is proximal to the communication device 50. Note that the WPAN device 60 may be a Bluetooth headset, a wireless microphone, a wireless speaker, a wireless display, and/or a wireless data entry unit.

In this embodiment, the communication device 50, which may be one of the communication devices 18-32 of FIG. 1 or another type of communication device, includes an integrated circuit (IC) 52 to communication with the cellular network, the WLAN, and/or the WPAN. Such a communication may include voice communications, audio communications, video communications, graphics communications, text communications, and/or data communications (e.g., emails, web browsing, short message services, etc.). For example, the communication device 50 may be receiving an audio file from the audio source 74 (e.g., a computer storing an MP3 file, a radio receiver, a cable set top box, a satellite receiver, a CD player, etc.), the server 66, and/or the PC 76 via the access point 54 as an inbound RF wireless network (WN) data signal 78. The IC 52 processes the inbound RF WN data signal 78 to produce inbound data that may be rendered audible by speaker circuitry of the IC 52 and/or communication device 50. Alternatively and/or in addition to, the IC 52 may convert the inbound data signal from the WLAN to an outbound RF WN data signal 80 that is provided to the WPAN device 60, which may reproduce the inbound data for presentation (e.g., render it audible).

As another example, the communication device 50 may be receiving a video file from the video source 72 (e.g., a computer storing a video file, a cable set top box, a satellite receiver, a DVDD player, etc.), the server 66, and/or the PC 76 via the access point 54 as an inbound RF WN data signal 78. The IC 52 processes the inbound RF WN data signal 78 to produce inbound data that may be presented on a display (e.g., speakers and LCD, DLP, or plasma display panel) of the communication device 50. Alternatively and/or in addition to, the IC 52 may convert the inbound data signal from the WLAN to an outbound RF WN data signal 80 that is provided to the WPAN device 60, which may reproduce the inbound data for presentation (e.g., play the video file).

As yet another example, the communication device 50 may record video, voice, and/or audio to produce a recorded file. In this example, the IC 52 may convert the recorded file into an outbound RF WN data signal 80 that is provided to the WLAN. The access point 54 recovers the recorded file and provides it to one of the other devices (e.g., PC 76, server 66, modem 70) for storage and/or forwarding onto the Internet.

As a further example, the modem 70, the PC 76, the server 66, the fax 64, and/or the printer 68 may provide a file to the access point 54 for communication to the communication device 50. In this instance, the access point 54 converts the file into the inbound WN data signal 78. The IC 52 processes the received the inbound WN data signal 78 to recapture the file, which may be presented on the communication device 50 and/or provided to the WPAN device 60.

As yet a further example, the communication device 50 may have a graphics, text, and/or a data file for communication to a component of the WLAN. In this example, the IC 52 converts the graphics, text, and/or data file into the outbound RF WN data signal 80 that is provided to the access point 54 and/or to the WPAN 60. In one embodiment, the access point 54 recovers the graphics, text, and/or data file and provides it to the PC 76, the modem 70, the fax 64, the printer 68, and/or the server 66. Note that the file may include an address that identifies which component(s) of the WLAN are to receive the file.

More examples include voice and/or data communications between the communication device 50 and the base station 56 in accordance with one or more cellular communication standards, which includes, but is not limited to, past, present, and/or future versions of GSM, CDMA, wideband CDMA (WCDMA), EDGE, GPRS, AMPS, and digital AMPS. For instance, the IC 52 may process outbound voice signals to produce outbound RF voice signals 88 and process inbound RF voice signals 84 to produce inbound voice signals. The IC 52 may facilitate the presentation of the inbound and outbound voice signals on the communication device 50 and/or transceive them with the WPAN device 60 as the inbound and outbound WN data signals 78 and 80. Further the IC 52 may process outbound data signals to produce outbound RF data signals 86 and process inbound RF data signals 82 to produce inbound data signals. The IC 52 may facilitate the presentation of the inbound and outbound data signals on the communication device 50 and/or transceive them with the WPAN device 60 as the inbound and outbound WN data signals 78 and 80.

The IC 130 may receive digitized voice-audio-&/or-video signals from the wireline connection 108 via the wireless port 138 or may receive RF signals via the antenna interface 140, where the IC 130 recovers the digitized voice-audio-&/or-video signals from the RF signals. The IC 130 may then compress the received digitized voice-audio-&/or-video signals to produce voice-audio-&/or-video files and store the files in memory 136. In the alternative, or in addition to, the IC 130 may convert the digitized voice-audio-&/or-video signals into analog voice-audio-&/or-video signals and provide them to the speaker 144 and/or to the display 142.

For outgoing non-real-time data communications, the keypad/keyboard 134 (which may be a keypad, keyboard, touch screen, voice activated data input, and/or any other mechanism for inputted data) provides inputted data (e.g., emails, text messages, web browsing commands, etc.) to the IC 130. The IC 130 converts the inputted data into a data symbol stream using one or more data modulation schemes (e.g., QPSK, 8-PSK, etc.).

As may further be used herein, inferred coupling (i.e., where one element is coupled to another element by inference) includes direct and indirect coupling between two items in the same manner as “coupled to”. As may even further be used herein, the term “operable to” indicates that an item includes one or more of power connections, input(s), output(s), etc., to perform one or more its corresponding functions and may further include inferred coupling to one or more other items.

As may be used herein, the term “compares favorably”, indicates that a comparison between two or more items, signals, etc., provides a desired relationship. For example, when the desired relationship is that signal 1 has a greater magnitude than signal 2, a favorable comparison may be achieved when the magnitude of signal 1 is greater than that of signal 2 or when the magnitude of signal 2 is less than that of signal 1.
